Quick Start
Required Equipment
• MAX17710GB20 EV kit
• Oscilloscope
• Precision voltmeter
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Verify that two shunts are installed on jumper JU1
(pins 1-2 and 3-4). Solar cells SOLAR1, SOLAR2,
and SOLAR3 are connected in parallel as the power
source.
2) Install a shunt in the 2-3 position on jumper JU2 to
connect the IC to the on-board MEC through a 10I
resistor. Important: The MEC (BATT) must always
be connected before the solar cell or damage could
result. Always connect JU2 first and disconnect JU2
last.
3) Install a shunt on jumper JU3 to connect the on-
board solar cells as the power source. The solar cell
voltage can be monitored on the SOLAR+ test point.
If verification with an external energy-harvesting
source is required, remove the shunt from JU3 and
apply the external power source to the SOLAR+ test
point. The power-source ground can connect to any
GND test point.
4) Connect the oscilloscope probe to the CHG test point.
The CHG test point is the output of the boost regula-
tor. Set the time division to 200ms and the voltage
division to 1V.
5) Under ambient light, the battery charges with a small
current. The oscilloscope displays voltage pulses
from the boost regulator. The boost output pulses
because of the solar cells’ limited current.
6) Increase the ambient light source on the solar cells and
observe the increase in frequency of pulses at the CHG
test point.
7) To turn on the internal regulator and enable the
battery pack output, press the S1 button.
8) Install shunts on jumpers JU5 and JU6. LED D5
pulses with the voltage pulses at the CHG test point.
D5 is a visual indication of the boost output.
9) To measure the MEC charging current, observe the
voltage across resistor R6. A precision voltmeter is
needed. The charging current can be as low as 1FA and
the voltmeter needs the precision to be able to pulse-
average over several seconds of data. An average volt-
age of 10FV indicates a 1FA average charging current.
